Are Yellow hornet harmful to humans?

The female wasp has a long thick stinger connected to the poison gland. The main components of the venom are some alkaline substances, including histamine, serotonin, bradykinin, hyaluronidase, etc. When it is stung, it will shoot venom into the skin of the person, but the sting needle is not left in the leather suit. After a person is stung by a wasp, the stinged skin will immediately become red, swollen and painful, even with petechiae and skin necrosis. When the eye is stung, it will cause severe pain, tearing, redness and swelling, and may also cause corneal ulcers. In addition, systemic symptoms include dizziness, headache, vomiting, abdominal pain, diarrhea, restlessness, and increased blood pressure. The above symptoms usually disappear within a few hours to several days. In severe cases, drowsiness, systemic edema, oliguria, coma, hemolysis, myocarditis, hepatitis, acute renal failure and shock.

Toxic to Animals

Yellow hornet has a sting which it uses defensively to inject a mild toxin. Adults of this species can sting when they feel threatened, but generally, their toxicity is considered mild. Humans, dogs, and cats may experience temporary discomfort and localized reactions upon being stung. Other insects such as bees and ants may also be affected by the sting, leading to disorientation or deterrence, limiting aggressive encounters. Examples and reactions to the toxin vary across species, with smaller animals possibly showing more acute symptoms.

European potter wasp
European potter wasp

The European potter wasp or European tube wasp (Ancistrocerus gazella) is a species of potter wasp. As an imago (adult), the female collects as many as 20 caterpillars for each nest, which consists of a single cell. Her larval offspring then feed on these inside the nest, which is sealed with mud arranged by her. As adults, they eat nectar and aphid honeydew. Males cannot sting, and the sting of a female is not painful. They can be found on windows, foraging for nectar on flowers, or searching out small cracks or holes in which to nest.
